Referring to FIG. 1, an application virtualization system 100 includes a user terminal 100 and a server 150 that are interconnected by a network 130. The user terminal 110 may execute the application program 111 and the application program 113. [ In addition, the user terminal 110 may wish to execute application program 115 in addition. When the hardware resources of the user terminal 110 are insufficient, the third application program 115 can be executed through the cloud service. The server 150 providing the cloud service receives the request for execution of the application program 115 from the user terminal 110 via the network 130 and transmits the application program 115 to the virtual machine Lt; / RTI >

If application 3 115 actually operates in a virtual machine on server 150, then the user of user terminal 110 via the virtualization service can access application 3 115 as if it were running on user terminal 110 Can be used. The input information input to the user terminal 110 for the application program 115 is transmitted to the server 150 through the network 130 while the application program 115 is running in the virtual machine on the server 150. [ ). ≪ / RTI > The application program 115 running on the virtual machine on the server 150 can receive and process the input information transferred to the server 150 through the network 130. [ The output information to be output through the display device or other output device while the application program 115 is being operated in the virtual machine on the server 150 may be transmitted to the user terminal 110 via the network 130. [ The user terminal 110 may output the output information transmitted from the server 150 through a display device connected to the user terminal 110 or another output device.

Referring to FIG. 2, an application program virtualization system 200 according to an exemplary embodiment of the present invention includes a user terminal 230, a server 250, and a display device 210. The display device 210 is connected to the user terminal 230. Similar to that shown in FIG. 1, the user terminal 230 and the server 250 are connected by a network, but the illustration of the network in FIG. 2 is omitted. In the following description, processes and procedures that are generally performed in a virtual desktop infrastructure or a cloud center are omitted.

Typically, when executing application programs in the user terminal 230, the operating system 237 stored in the storage device 239 inside the user terminal 230 is driven, and then stored again in the storage device 239 And loads the application software. However, if the performance of the user terminal 230 is insufficient, it may not be executed smoothly when a plurality of application programs are executed. As described above with reference to FIG. 1, in this case, a specific application program may be executed by the virtual machine 251 on the server 250 according to the selection within the user terminal 230 or the user's selection. In the example shown in Fig. 2, application program 252 has been selected to run in virtual machine 251. Hereinafter, an application program virtualization system 200 according to the present invention will be described with reference to each component.

The user terminal 230 may include a virtual terminal agent 231. The user terminal 230 may also run the operating system 237 to execute the application programs 233 and 235. In one embodiment, the virtual terminal agent 231 may be configured as a separate device within the user terminal 230. [ In this case, the virtual terminal agent 231 may be implemented as a semiconductor device such as a microprocessor, a central processing unit, or the like, and may be implemented as an operating system 237, an application program 233, Can be configured as separate devices. In another embodiment, the virtual terminal agent 231 may be implemented by a device that drives the operating system 237, application 1 233, and application 2 235. For example, one central processing unit may operate the operating system and may drive the application program 233, the application program 235, and the virtual terminal agent 231 under the operating system. The virtual terminal agent 231 can communicate with the virtual machine 251 of the server 250 and execute the application program 252 in the virtual machine 251 in the user terminal 231. [

The user terminal 230 may have an operating system 237 and a plurality of application programs 233, 235, and 252. To this end, the storage device 239 of the user terminal 230 is responsible for installing and executing the operating system 237 to be executed in the user terminal 230, and installing and executing the application programs 233, 235, For example. The storage device 239 may be implemented by various devices such as a hard disk drive (HDD), a solid state drive (HDD), and the like.

The virtual terminal agent 231 is configured to forward data associated with the operating system 237 and data associated with the application to the server when the user terminal 230 requires execution of the application program via the virtual machine 251 . For example, as shown in Figure 2, the user terminal 230 directly executes application 1 233 and application 2 235, and causes application 3 252 to run on virtual machine 252 The virtual terminal agent 231 can deliver the executable files of the operating system 237 and the executable files of the application program 252 stored in the storage device 239 to the server 250 . Therefore, according to the embodiment of the present invention, the virtual machine 251 operating in the server 250 can use the operating system and the application program software in the user terminal 230 as it is, The application 3 252 can be executed in the same environment as the application program 252.

In the embodiment shown in FIG. 2, data associated with operating system 237 and application program 3 252 are stored in a single storage device 239. According to an embodiment, the user terminal 230 may include a plurality of storage devices, and when data related to the operating system 237 and the application program 252 are divided and stored in the plurality of storage devices, The terminal agent 231 can access all of the plurality of storage devices and relay the data to the server 250. [

The display device 210 is connected to the user terminal 230. Although FIG. 2 illustrates that the display device 210 is configured separately from the user terminal 230 for convenience of illustration, the user terminal may include a display device or may be integrally implemented according to an embodiment . Also, although not shown in FIG. 2, an input device for a user's input, such as a keyboard or a mouse, may be connected to the user terminal 230. Depending on the user's operation, the display device 210 may display all or a part of the application programs 233 and 235 executed in the user terminal 230. [ For example, the display apparatus 210 processes the output information output from the application program 233, displays it in the application program 1 display area 211, processes the output information output from the application program 235 And can be displayed in the application program 2 display area 213. In the application program virtualization system 200 according to the embodiment of the present invention, the display device 210 displays the output (s) received from the application program 252 executed by the virtual machine 251 driven by the server 250 Information can be displayed in the application program 3 display area 215. [ The display device 210 may display all the screens related to the operating system 254 and the application program 252 that are running in the virtual machine 251 and may also display a screen showing only the application program 252 May be displayed.

In this manner, the input information for driving the application program 3 (252) is input in the same manner as the input information for driving the application programs 1 and 2 (233, 235) Is displayed or outputted in the same manner as the application programs 1 and 2 (233, 235), so that the user can use the application program 252 without any difference in the case of executing the application program 252 in the user terminal 230, The performance of the user terminal 230 can be improved because it is leased from the server 250.

The server 250 may be at least a part of a cloud center or virtual desktop infrastructure system. The server 250 may include a hypervisor 253 and the hypervisor 253 may be coupled to the virtual machine 251 based on data associated with the operating system 254 delivered from the virtual machine 231 of the user terminal 230. [ ). ≪ / RTI > The hypervisor 253 also allows the virtual machine 231 to execute the application program 252 based on the data associated with the application program 252 delivered from the virtual machine 231 of the user terminal 230 .

The virtual machine 251 may boot based on the relayed data from the hypervisor 253 and execute application program 252. [ The data for driving the application program 252 among the data input by the input device connected to the user terminal 230 is transmitted to the virtual machine 251 of the server 250 through the network by the virtual terminal agent 231 Application 3 252 being executed, and application 3 252 being able to operate based on the input data. Data output according to the operation of the application program 3 252 is transmitted to the virtual terminal agent 231 of the user terminal 230 through the network and the virtual terminal agent transmits the output data to the display device 210, And displayed in the program 3 display area 215. [

The cloud data center (CDC) management unit 255 may control the virtual machine 251 of the server 250. [ Although not shown in FIG. 2, the server 250 may drive a plurality of virtual machines, and the virtual machine management unit 256 of the CDC management unit 255 may control the driving of the plurality of virtual machines. For example, in one embodiment, when a plurality of user terminals connected to the server 251 request creation of a virtual machine, the requests are accepted by the virtual machine management unit 256 of the CDC management unit 255, The virtual machines requested by the control of the machine management unit 256 can be created and operated. In addition, when the virtual machines are driven and the user terminals request the virtual machine termination, the virtual machine management unit 256 may delete or terminate the corresponding virtual machine in response to the request.

3 is a block diagram illustrating a virtual terminal agent according to an embodiment of the present invention.

3, the virtual terminal agent 300 according to an exemplary embodiment of the present invention includes a virtual machine management request unit 310, an application control unit 330, a storage access control unit 350, an input information processing unit 370, And an output processing unit 390.

The virtual machine management requesting unit 310 may perform a function of requesting creation of a virtual machine or requesting deletion to the server side (CDC or VDI center) according to a user's request or a determination in the user terminal. Upon request of the virtual machine management request unit 310, the private network may directly access the designated hypervisor API to perform the request. In the example of FIG. 2, the virtual machine management request unit 310 may transmit the requests to the virtual machine management unit 256 of the CDC management unit 255.

The application control unit 330 may execute and control an application program designated to operate in the virtual machine.

The storage apparatus access control unit 350 plays a role of relaying the storage apparatus 239 so that the storage apparatus 239 can be accessed. The storage access control unit 350 may separately manage cache and operation information generated when the user terminal and the virtual machine operate at the same time, thereby preventing conflicts. In yet another embodiment of the present invention, the storage access control unit may further introduce a method of caching the storage information of the user in a situation where the image transmission of the operating system is not smooth or in a way to increase the efficiency. In this case, the user can reduce the transmission process of the operating system in the future connection.

The input information processing unit 370 can identify an input related to an application program executed on the virtual machine and transmit the same to a virtual machine to be applied to an executed application program. In the example of FIG. 2, a plurality of data are input through an input device connected to the user terminal 230. Among them, input data for driving the application program 252 is identified by the input information processing unit 370, 250). The input data transferred to the server 250 is input to the application program 252 and processed.

The output processing unit 390 receives the screen of the virtual machine and displays only the screen of the application program on the display device or the output device of the terminal. At this time, the output device may be an audio device, a printer, or the like as well as a screen. For example, in the example of FIG. 2, data output from the application program 3 252 is transmitted to the virtual terminal agent 231 of the user terminal 230 via the network, and in this case, The output data may be transmitted to the display device 210 and output to the application program 3 display area 215.

4 is a flowchart illustrating an example of an application program virtualization method according to the present invention.

Referring to FIG. 4, an application program virtualization method according to the present invention includes determining (S110) use of a virtual machine, requesting creation of a virtual machine (S111), information related to an operating system, A step S114 of controlling the start of the application program, a step S115 of processing the input information, a step S116 of processing the output information, a step S116 of processing the output information, Terminating the program (S117), and terminating the virtual machine (S118).

The step of determining the use of the virtual machine (S110) may be performed on the user terminal side as described in Fig. This process may be performed by a virtual machine use decision input inputted by the user or may be performed by an internal decision of the user terminal. When performed by a virtual machine usage decision input entered by the user, whether to use the virtual machine may depend on an arbitrary decision of the user terminal user. For example, if the user recognizes that a specific application program needs to be executed through a virtual machine separately from the actual resource status of the user terminal, the use of the virtual machine can be determined through the input device connected to the user terminal. In another embodiment, for example, if the resource of the user terminal is determined to be scarce, the user terminal may decide to use the virtual machine by itself.

The step S111 of requesting the creation of the virtual machine may be performed by transmitting a virtual machine creation request message from the user terminal to the server as described above. In particular, the virtual machine management request unit 310 of FIG. 3 may transmit the virtual machine creation request message to the CDC management unit 255 of FIG.

The step S112 of transmitting information related to the operating system and information related to the application program may be performed on the user terminal side. 2, the virtual terminal agent 231 reads the executable files of the operating system stored in the storage device 239 and the executable files of the application program 252 (step S212) To the server side. In this case, the information related to the operating system may be executable files of the operating system, and the information related to the application program may be executable files of the application program.

In another embodiment, the information associated with the operating system may be memory information of the operating system loaded into the memory device of the user terminal. An embodiment related to this will be described in more detail below with reference to FIG. 7 and FIG. In addition, the information related to the operating system may be identification information of the operating system. An embodiment related to this will be described in more detail below with reference to Figs. 8, 9 and 12. Fig. The information related to the application program may be identification information of the application program.

The step S113 of creating a virtual machine may be performed on the server. As described above, the CDC management unit 255 in FIG. 2, particularly the virtual machine management unit 256, can perform the above-described step S113. The virtual machine may be booted based on the information related to the operating system transmitted in step S112. In the embodiment of FIG. 4, although it is shown for convenience that information related to an application program is transmitted before creation of a virtual machine, information related to the application program may be transmitted after creation of the virtual machine.

The step S114 of controlling the start of the application program can be performed by the virtual machine. The virtual machine may execute the application program based on the information associated with the application program received in step S112.

 In the input information processing step S115, the input information processing unit included in the virtual terminal agent of the user terminal identifies information for the application program executed in the virtual machine among the information input through the input device connected to the user terminal It can be transmitted to the server side. The input information received at the server is transferred to the application program of the virtual machine and processed by the application program.

In step S116 of processing the output information, the virtual machine of the server transmits the output information output from the application program to the user terminal through the network. The output processor included in the virtual terminal agent of the user terminal may transmit the received output information to the display device so that an indication related to the application program running in the virtual machine is output.

The processing of the input information (S115) and the processing of the output information (S116) may be performed in parallel while the application program is running on the virtual machine.

The termination of the application program (S117) may be performed at the request of the user terminal. For example, when a virtual terminal agent of a user terminal receives an instruction to terminate an application program running on the virtual machine, the application terminal can transmit a request to terminate the application to the virtual machine of the server.

The step of terminating the virtual machine (S118) may be performed at the request of the user terminal.
